How To Convert Rar File To Zip In Windows

Do you have some RAR files that you want to convert into ZIP files? Learn how to convert RAR file to ZIP.

Both RAR and ZIP files are popular file formats that allow you to store files in a compressed manner. Hence, the files take less space and can be transferred swiftly if needed.

When you have some RAR files that are already compressed, you might still want to convert them into ZIP files due to various reasons. Read this article to know how to convert a RAR file to ZIP. But first, let’s go through a brief discussion on RAR and ZIP files.

What Is a RAR File?

Just like the ZIP file, the RAR file is also a compressed archive file format. It can also store one or more files in a compressed format. RAR files were invented by Eugene Roshal in the 1990s.

While RAR files can compress large files and folders, the resultant files they create are smaller than ZIP files. Hence, you can enjoy faster file transfers and reduced storage space. To create and open RAR files, you can use software programs like WinRAR, 7-Zip, and WinZip.

RAR files support password protection and can split large archives into multiple volumes. These features often make RAR a popular choice for archiving and transferring large files.

What Is a ZIP File?

A ZIP file is a popular file format that can compress files before archiving them. You can turn any file (one or more) into one smaller file through zipping. ZIP files were invented by Phil Katz that became popular because of reduced file size and its ability to get transferred easily through the internet.

Even when it compresses large files to a smaller size, there is no change in data quality or integrity. If you have a ZIP file, you can extract its items using various programs and tools like the built-in Windows tool for compressed folders, WinZip, 7-Zip, and WinRAR.

How RAR Files and ZIP Files Differ From Each Other

The main difference between RAR and ZIP file formats is the compression algorithm they use. RAR files use a proprietary compression algorithm developed by RARLAB. People usually consider this to be more efficient than the ZIP file’s compression algorithm. It’s also the reason RAR files can often have higher compression ratios than ZIP files and deliver files of smaller sizes.

Features RAR File ZIP File

Compression Algorithm Uses proprietary RAR algorithm, often more efficient than ZIP algorithm Uses a standard ZIP compression algorithm

Compression Ratio higher compression ratio than ZIP files Lower compression ratio than RAR files

License Need proprietary software with a limited free trial Can be created and extracted with free, open-source software

Popularity Less popular than ZIP files Widely popular and supported

Ease of Use Creation and extraction require specialized software Built-in support in most operating systems

Password Protection Supports strong password protection Password protection feature is available

Error Recovery Supports error recovery, can repair damaged archives Has no built-in error recovery feature

Top Reasons to Convert RAR File to ZIP Format

ZIP files are more widely supported than RAR files. So, some operating systems or applications may not be able to open or extract RAR files. By converting RAR files to ZIP file, users can easily open and extract them.

While sharing a file, it is more convenient to use a file format that is more commonly used and supported. If you convert a RAR file to a ZIP file, others can easily access and use the file.

How to Convert RAR File to ZIP Convert RAR to ZIP Using WinRAR

Make sure to install the WinRAR application on your computer.

Select Show more options.

Hover over WinRAR option and select Extract to “filename/” from the context menu.

The files will be extracted as a regular folder.

Select Add to archive… option.

Under the General tab, select the ZIP button and enable other settings of your choice.

Convert RAR to ZIP Using 7-Zip

You can also use the 7-Zip software to convert RAR files to ZIP files. This tool also has to be downloaded and installed on your computer before performing these steps:

Select the RAR file that you have to convert to a ZIP file.

Hover over 7-Zip and select Extract to “filename/”.

Now select the extracted folder and select Show more options.

Hover over 7-Zip and select Add to archive option.

In Add to Archive window, select zip from Archive format drop-down menu.

That’s it. You can easily convert RAR to ZIP format.


If you’re about to share a RAR file, the recipient might have trouble opening it without the proprietary software. For this reason, it’s better to convert RAR to ZIP format. In this article, I’ve discussed the difference between these two file formats, along with some techniques to convert RAR file to ZIP.

How To Show File Extensions In Windows 11/10

File Extension is that which identifies the file type. If you are a regular Windows user, then it is not at all a problem to identify the file type. For it is very important to see file extension to identify the type of file you are trying to open from a security point of view. So in this post, we will see how to hide or show File Extensions in Windows 11/10/8/7 and why you should show them.

What are File Extensions & how are they useful

Different file types have different extensions. Audio files have .mp3, .wav, .wma, and more based on the program used to open that file. File extensions also help the operating system to identify the corresponding program to open that particular file. So, you should be able to see file extensions to be at the safer side, and we will let you know how to enable options to see file extensions in Windows.

As mentioned earlier, by default Windows does not show file extensions and they are hidden. But, you can toggle the option to see them.

Show File Extensions in Windows 11/10

There are five ways how you can go about accessing this setting:

Once here, you can do the needful as explained above.

These are very simple steps to follow, and you do not need any third-party software to view file extensions. Windows provides us with everything which can be easily achieved, and the point lies in knowing and implementing them. This is the first way to see file extensions in Windows 7.

Start by hitting the WINKEY + X combinations and select Command Prompt (Admin) to launch Command Prompt with Administrator Privileges.

Navigate to the root location of that bootable device inside the Command Prompt command line. Once you get there, type in the following to show the file extensions-

reg add HKCUSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced /v HideFileExt /t REG_DWORD /d 0 /f

And then hit Enter.

You can also enter the following command to hide the file extensions,

reg add HKCUSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced /v HideFileExt /t REG_DWORD /d 1 /f 5] Using Group Policy Editor

You can also use the Group Policy Editor and change the setting here:

How To Activate Windows 11 Or Windows 10

In this post, we will see how to activate Windows 11/10. Activation is the initial process by which a Windows running on a PC is determined to be properly licensed and genuine, and it’s really quick and easy. It is different from Registration, in the sense that,  Activation is the process of ensuring that your copy of Windows is used according to the Microsoft Software License Terms, whereas registration is the process of entering information to sign up for product support, tools, and tips, and other product benefits.

It’s a great time to talk about Windows activation and how it will work. For customers who are already familiar with activating Windows 11/10, this will feel pretty familiar, and, as far as the user experience goes, it’s not too different from earlier Windows versions.

You can activate either online or by phone.

When you install Windows and log in with the user account, Windows will ask you to activate it. It’s a process through which Microsoft figures out if the copy of Windows is legit. Activation is easy, and it can be done through a Windows key or linked Microsoft account, and even transfer the key from an old machine to a new one if it’s a connected account. However, if you are facing an activation issue, this post will guide you on how to activate Windows 11 using multiple methods.

How to Activate Windows 11

You can use any of the following methods to activate your copy for Windows 11.

Run Activation Troubleshooter

SLMGR Command

Use your Microsoft Account

Before you go ahead with any of the steps, ensure that you have a proper internet connection and restart the system at least once. At times activation gets stuck, and this can help to resolve. Also, you will need an admin account before using these methods.

1] Run Activation Troubleshooter

Windows will then run the wizard and internal programs to resolve the problem.

If essential troubleshooting works, and the activation key entered earlier or linked to Microsoft account is valid, Windows should get activated.

2] SLMGR Method

SLMGR or Software Licensing Management Tool is a tool that can run commands to activate Windows. It is available for Windows users as well, and anyone can use it. You will need to use the Windows key using this method.

Keep a copy of the Windows key in the clipboard and notepad.

Open Run prompt using Win + R and then type WT followed by pressing the Enter key.

Type and execute the command slmgr.vbs /upk  to remove previously installed key.

It will then use the key to connect with the Microsoft licensing server, validate it, and activate it.

SLMGR command may not be available for Windows Home users.

3] Sign-in with Microsoft Account

When installing Windows 11, if you have used a local account, and your key is connected to your Microsoft account, you need to use it. Once the Windows key is digitally linked with Microsoft account, you can activate it or transfer it to any PC.

Expand the Activation State

If you have previously linked your Windows with a Microsoft account, then it will instantly activate your copy of Windows 11.

Activate Windows 10

To activate Windows 10 OS do the following:

Activate Windows 11/10 after a hardware change

If you face issues after a hardware change, then this post shows how to activate Windows after a hardware change.

How long can you use unactivated Windows?

There is a 30 days evaluation period during which everything works. There will be a watermark available on the desktop until Windows is activated. Ensure that if you are evaluating Windows, keep a backup up of all documents and important files.

What happens if you don’t activate Windows?

A couple of things will happen. You will receive a notification that “Windows is not activated, please activate Windows now.” in Settings. In addition to the lock screen and wallpaper, you will not change accent colors, themes, etc. You won’t be able to modify anything related to Personalization. Some apps and features may cease to function. In a couple of months, I will start rebooting randomly.

How can I activate my Windows 11 for free?

Short Answer, you cannot. However, you can transfer your Windows 10 License to Windows 11 as the upgrade process is free if it’s the same version of Windows. If you don’t have the key and perform a fresh install, first ensure to connect the Microsoft account on Windows 10. Once done, upgrade, and then again use the same account in Windows 11.

How To Send Large Files In Windows 10 And 11

Email is probably your first port of call, but providers are very strict when it comes to attachment size limits. It’s just 20Mb on Outlook or 25Mb on Gmail and Yahoo. That won’t cut it for large files – even a few full-res photos will take you over that mark. 

Then there’s messaging apps, but the situation is only slightly better here. WhatsApp, Facebook Messenger and Signal all won’t let you send files larger than 100Mb. 

So, what should you do? Here are four easy ways to safely and securely move a file from File Explorer to someone else’s computer. We’re using Windows 11 for the purposes of this tutorial, but all the following methods also work on Windows 10. 

Tip: Connect to a VPN first

When you use a VPN, the type of files you’re uploading can’t be detected, meaning no limitations will be put on speeds. However, do be aware that some VPNs still affect connection speeds slightly. 

See our best VPN chart for some great options, with NordVPN currently top of the list. 

Zip and unzip

In an ideal world, you’d want to continue using your preferred email provider or messaging app. Zipping files lets you do that, compressing them down to a fraction of their original size. After downloading it, the recipient then just needs to extract the files and they’ll work just like normal. 

To zip files in Windows: 

Open File Explorer and select all the files you’d like to send 

Anyron Copeman / Foundry

Once complete, a new folder with a zip icon will be created. Give it a name of your choosing and hit enter

Anyron Copeman / Foundry

Send to the recipient, attaching it in the same way you would any other file 

However, this won’t work for all files. As you can see from the screenshot below, the zipped file is still almost 300Mb – far too big for emails. In that situation, you’ll need to look at alternatives. 

Use a third-party website

Fortunately, there are lots of websites which let you send large files for free. WeTransfer is the most popular, although you’ll have to pay $120/€120 for anything more than 2GB (up to 200GB). has a more generous 6GB maximum, while Send Anywhere and Smash have no limits at all. 


Use a cloud storage service

If you already have an account with a cloud storage service, it makes sense to use it to send large files. 

Provided you have the spare capacity to upload it, there’s no limit on the size of files which can be shared via Google Drive or OneDrive. They can be shared with specific users, or you can create a unique link to share with anyone you’d like to be able to access it. 

The latter is also available via Dropbox, although you can’t send files bigger than 100GB unless you purchase an add-on. Stil, this will be plenty for most people. 

Use Telegram

If you regularly send large files to friends and family, it might be time to reconsider which messaging app you use. WhatsApp, Facebook Messenger and Signal are all very limited in this regard, but Telegram is the exception.  

The latter lets you upload and send files up to 2GB in size, plus store them for free on the Telegram Cloud. If that’s not enough, signing up for Telegram Premium ($4.99/£4.99 per month) increases this limit to 4GB. 

What’s more, there’s no need to make it your primary messaging app if you don’t want to. A mobile number is required to sign up, but it can then be used as a standalone service on Windows, macOS, Linux and even via the web. 

Use an external storage device

The final option is one you might not have considered, and it only works if the recipient is nearby. Transferring the files to a USB stick or external hard drive is an easy way to move them to someone else’s device.  

If this is an option for you, look for something with high read and write speeds, such as an SSD. This will ensure the files are transferred as quickly as possible.
